In looking at this lovely black stallion, I think he has wonderful feet and legs and unless your mare has any problems, they should cross well. We had an anglo morgan foal and she was gorgeous, their are alot of similarities in the breeds, of course there is a lot of Arabian in the Morgan lines. Cross breds are very vigerous and it seems that most often the good traits of each come through. I think they call this Hybrid vigor. We have many crosses, mostly Moran-Arabian, but one cannot go wrong with Arabian blood. Contrary to popular belief, they are easy to work with, especilly if they have grown up with you. Handling and teaching the basics, building that bond when they are young, is so important. Arabian are very intellegent and I think you will find a great cross with your mare. She looks lovely int he picture. I bet you are so excited. It is a sense of great accomplishment when that foal is on the ground. Then the real fun begins!
Most foals with tendon problems out grow it soon after birth. I know of a foal who was born wish almost deformed legs because he was so big in his mother, it took nearly six months for him to walk properly. That was an extreme case. You should see him now. A beautiful palimino. One would never know what his owner went through with him. She consulted vets on line at the time and they all advised her to let nature take it's course. I had a little filly last year from an older arab mare that actully toed out. Her mother toed in. Now she is nearly perfect. Maturity brings changes. That is why I believe horses should get their proper growth before being ridden a great deal.
